where to install 12v water pump in camper

How about between the water tank and the tap? Have the flow indicator pointing towards the tap. There are no rules, have fun.

Close to the tank Baz&Mak so if it gaet something under a valve in the pump it doesn't have a great head to lift water to the pump

Thanks guys,It was a silly question i know but i was just worried about mud and salt water stuffing it up, if i were to install it under the traileri open to the elements

Baz & Mak,
I don't think it makes that much difference where you install it providing you use a pump to do the job you wan't.What i would also do is to install an on/off switch to the pump as most systems are under pressure when the tap is turned off and if you get a leak while travelling or when the camper is folded up you could end up with a very wet camper.Iinstalled a switch near the battery which Iturn off when the camper is not in use which gives me eliminates any leakage problem.

Hi Baz&Mak

don't think I would put it under the camper - somewhere protected - perhaps inside is a much better idea IMO - under a seat, cupboard, battery compartment or in some other hatch.

Most pumps have a lot of plastic and wont last long on a gravel road. You mention salt - the pump, your wiring and the connectors probably wont last long either if directly exposed to salt & moisture outside.

Have a pump installed in a cupboard no trouble - connected to 2 tanks through a y tap connector - most pumps can lift a bit - might take a little time to prime on first use after an empty tank - they have non return valves so it doesn't happen each use.

Hope this helps
